octeontx2-pf: QOS: Perform cache sync on send queue teardown

Browse source

[ Upstream commit 479c580160 ]

QOS is designed to create a new send queue whenever  a class
is created, ensuring proper shaping and scheduling. However,
when multiple send queues are created and deleted in a loop,
SMMU errors are observed.

This patch addresses the issue by performing an data cache sync
during the teardown of QOS send queues.
